Figure 3. Communication Wiring. Controller LED Indicators The controller has six Light Emitting Diode (LED) indicators.
Product Overview Siemens Building Technologies, Inc. 5 Pressing the Emergency Purge button a second time reverts the Fume Hood Controller to normal operation for the current conditions.
Fume Hood Controller Owner's Manual 6 Siemens Building Technologies, Inc. The terminal is available in diameters ranging from 4 to 18 inches. The terminal is available in a variety of end configurations to match the duc twork construction. It is also available in TEFLON ® coated 18-gauge steel for highly corrosive environments.
Product Overview Siemens Building Technologies, Inc. 7 High Speed Electronic Actuation The High speed electronic actuator assembly cons ists of two parts, t he electronic actuator and the interface board. The actuator is connect ed to the exhaust flow control device in the fume hood exhaust duct.
Fume Hood Controller Owner's Manual 8 Siemens Building Technologies, Inc. Low Speed Electronic Actuation Alternately, when speed of response is not an issue, slower speed electronic actuation may be used. This can be used when the change-of-s tate between High and Low can take place in 15 seconds or more.
Product Overview Siemens Building Technologies, Inc. 9 Figure 8. Pneumatic Actuator. Analog Output-Pneumatic (AO-P) Module The Analog Output-Pneumatic (AO-P) Module is an electric-to-pneumatic interface between the Fume Hood Controller and the pneumatic actuator.
Fume Hood Controller Owner's Manual 10 Siemens Building Technologies, Inc. NOTE: While the pneumatic actuator is bei ng commanded, you may hear a hissing or clicking sound coming from the AO-P module. This is due to the movement of the air valves and the bleeding of air from t he actuator.
Siemens Building Technologies, Inc. 11 2 Applications Fume Hood Controller: 2-Position Constant Volume Application 940 is designed for use with a cons tant volume or two-position fume hood in a manifold fume hood exhaust system.
Fume Hood Controller Owner's Manual 12 Siemens Building Technologies, Inc. Basic Operation The Fume Hood Controller provides Direct Di gital Control (DDC) technology for controlling fume hood face velocities in a manifolded fume hood exhaust system.
Applications Siemens Building Technologies, Inc. 13 DO3 Output Functionality DO3 is designed to operate in two different m odes. DO3 can follow the alarm status of the controller by turning ON during alarm condi tions and OFF during normal operation; or DO3 can follow the HI.
Fume Hood Controller Owner's Manual 14 Siemens Building Technologies, Inc. Alarm Strategies One approach is to use the ALARMs to indicate a condition that requires immediate attention and the WARNINGs to indicate a condition that may require attention but is not urgent.
Applications Siemens Building Technologies, Inc. 15 The fume hood operator may silence the horn by pressing the Horn Silence button on the ODP without affecting the Emergency Purge sequence. In addition to the ODP indicators, the emergency alarm point will toggle to ON and will remain ON until the sequence is canceled.
Fume Hood Controller Owner's Manual 16 Siemens Building Technologies, Inc. In addition to setting up the purge sequence to effectively handle the exhaust needs, decisions must be made on how to use the info rmation available at the central reporting station.
Point Database Siemens Building Technologies, Inc. 17 3 Point Database Chapter 3 presents a description of the Fume Hood Controller point database including point descriptors, point addresses, and a listing of applications in which each point is found.
Fume Hood Controller Owner’ s Manual 18 Siemens Building Technologies, Inc. Address Descriptor Description 15 EMER STPT A value of the preset FLOW STPT, in percent, that the controller uses as the setpoint when EMER ALM is ON. 16 LOW WARN This point displays an ON or O FF status.
Point Database Siemens Building Technologies, Inc. 19 Address Descriptor Description 56 ODP STPT SW Indicates if the lowe r left butt on on the ODP has been pressed. This is a toggle action digital input; when pressed, t he controller changes betw een HI and LOW flow setpoints.
20 Siemens Building Technologies, Inc. 4 Troubleshooting This chapter describes corrective measures you can take should you encounter a problem when using the Fume Hood Controller. For issues not covered in this section, contact your local Siemens Building Technologies, Inc.
Troubleshooting Siemens Building Technologies, Inc. 21 Safety Features The controller board stores the controller's addr ess, applications, and point values. In the event of a power failure or a reset, these val ues are retrieved from the controller’s permanent memory and are used by the controlle r unless overridden by a field panel.
